Application le. May 8, 1920.

To all whom it may concern:

Be it known that I, HARRY C. FRATT, a citizen of the United States,residing at Norristown, in the county of Montgomery and State ofPennsylvania, have invented new and useful Improvements inRefrigerators, of which the following is a specification.

This invention relates to refrigerators, and has for its primary objectthe provision of means to eliminate the accumulation of moisture withinthe outer casing and afl-'ecting the packing therein and thus maintainthe latter in a clean and sweet condition.

Ubjectionable odors which are frequently found in refrigerators, arecaused by the accumulation of moisture in the outer casing of therefrigerator, this moisture saturating the packing in said outer casingand keep ing the latter in a very unsanitary condition. rllhedisposition of the packing is such that access cannot be readily had tothe same, and consequently in due course of time this packing throwsofi' an odor which is very objectionable. Cleaning of the interior ofthe refrigerator does not destroy the odor which as above stated isemitted from the packing in the outer casing.

In carrying ont the invention, I line the interior of the outer casingwith metal or other suitable material which prevents the moisture fromgaining access to the packing, and Space the inner casing from' saidlining, thus defining a dead air chamber between the inner and outercasings, which chamber tends to dry the moisture which enters thechamber from the inner casing.

Another object of importance resides in the construction of arefrigerator having normally closed openings in the top and front wallthereof, which permits the air chamber to be properly cleaned whendesired. y

The nature and advantages of the invention will be better understoodwhen the following detailed description is read in connection with theaccompanying drawing, the invention residing in the construction.combination and arrangement of parts as claimed.

In the drawing forming part of the application, like numerals ofreference indicate similar parts in the several views, and wherein:

refrigerator constructed in accordance with my invention.

`F ig. 2 is a horizontal sectional view therethrough.

Fig. 3 is a fragmentary front elevation.

Fig. 1 is a sectional view through the top wall thereof.

Referring to the drawing in detail, the refrigerator is indicatedgenerally at A., and includes an outer casing l() and an inner casing11. The outer casing is lined with metal or other suitable materialwhich will prevent moisture from gaining access through the packingwhich as shown is interposed between the lining 12 and the outer casing,the packing being indicated at 13. The inner casing 11 may be of anysuitable construction and design, but in accordance with my invention isspaced from the lining 12, the intervening space between the innercasing 1l and the lining 12 defining a'dead air chamber which tends todry the moisture which enters the space or chamber 14 from the innercasing 11. Consequently, the packing 13 cannot be affected by moisturewhich passes through the wall of the inner casing 11, and which factserves to maintain not only the packing 13 but the refrigerator in itsentirety in a sweet and clean condition. For the purpose of gainingaccess to the chamber' 1li, when it is desired to cleanse the latter, Ipreferably provide the top wall of the refrigerator with an opening 16which is normally sealed by the closure` 17, the front wall being alsoprovided with an opening 18 normally sealed by the closure 19. Theopening 16 is of a size to permit the insertion of a hose or the like tointroduce water or any other cleaning agent into the chamber 14 at thetop thereof, so that the interior of the chamber may be properlycleaned, the water or cleaning agent passing out through the opening 18.

While it is believed that from the foregoing description the nature andadvantages of the invention will be readily apparent, I desire to haveit understood that I do not limit myself to the details herein shown anddescribed, and that such changes may be resorted to when desired as fallwithin the scope of what is claimed.

That I claim is:

A refrigerator comprising spaced inner and outer casings, a metalliclining for the outer casing, the lining being spaced from the Walls ofthe inner and outer casings and defining an air chamber between the sameand the casing, packing interposed between the lining and the Wall ofthe outer casing, the top of the refrigerator having an openingcommunicating with said air chamber, a

plug removably fitted in said opening, the front Wall of therefrigerator having; an elongated opening communicating with the 10 saidair chamber, and a closure for the latter mentioned opening.

In testimony whereof l nfiix my signature.

HARRY C. F RATT.
